In this highly competitive and somewhat musical episode of EightyPercentMental, we talk with Dr Josephine Perry, a sport psychologist who literally wrote the book on Performing under Pressure, and Jo Davies, who runs a private practice consultancy focusing on sport psychology, wellbeing, and personal development. We try to get to the bottom of why it is that we get nervous, what anxiety actually is, and what we can do to manage nerves when they become unhelpful for performance.
